To a/ZZ whom it nfl/ty concern: p

` Be itnknown that I, HORACE FALK NEU- MEYER, a citizen ofthe United States, residing at Macungie, in the county of Lehigh and State of Pennsylvania, have invented a new and useful Wall-Hydrant, of which the following is a specification. r

My present invention relates to a novel wall-hydrant designed primarily to facilitate the attachment of a hose to the water-pipes of a house for the washing of sidewalks and streets, the watering of lawns, dac.

The objects of Ithe invention are numerous, but are, primarily, to render the hydrant antifreezing, to maintain absolutely water-tight connections at the valve or plunger and around the plug, and to simplify the construction and arrangement ofthe elements of the device in a manner tto facilitate its attachment to the Wall of a building and to enable it to be easily repaired.

To theaccomplishment of these ends the invention consists in the construction and arrangement of p'arts hereinafter fully'de.

scale, and Fig. 4 is a transverse sectionalv view on the line 4 4 of Fig. 2.

Referring to the numerals of reference em-` ployed to designate corresponding parts in the several views, 1 indicates a wall through which extends a horizontally-disposed wallpipe 2, constituting the body of my hydrant.;

The outer end of this pipe is` threaded for at. tachment to the internally-threaded pipe connection 3, constituting a feature of a facecasting 4. The casting 4 comprises, in addi tion to the connection 3, a face-plate 5, de-

signed to lie flat upon the outer surface of' the wall, and a hose-nipple 6, extended from the face-plate and communicating with the .connection 3 through a way 7, which latter is an integral section of piping of compara` `when the nut is screwed home.

Itively-small diameter extending in the rear of the face-plate 5 to the connection 3. The face-castin g is also provided with a cylindrical plug-socket 8, coaxial with the wall-pipe 2 and closed by-a hollow face-nut 9, screwed into the outer end of the socket and having its insertion therein limited by an annular ange 10, which bears against the face-plate The facenut is designed for the protection of the keypost 11, extending through an opening 12 in the bottom wall of the nut and formed as an integral part of a rotary plug 12, extending through the bottom wall 13 of the plug-socket 4 and provided between said wall and the Wall12b of the nut with an annular flange or head 14, urged against a leather or other compressible packingring 15 by a spiral spring 16, interposed between the plug and a face-nut. The packing-ring 15 fits snugly upon the plug and is normally compressed against the wal1l3 of the plugsocket in a y manner to form a water-tight connection between the plug and the opening in the wall 13through Which said plug passes. In this manner the escape of water from the wallpipe around the plug is absolutely prevented, which eliminates the objectionable corrosion of the connection between the face-nut and casting, which corrosion ordinarily serves to render it exceedingly diicult to disorganize the elements of the hydrant for the purpose of repair.

The plug 12a isvdesigned to be .rotated by the application of the usual key to the keypost 1l and is recessed axially from its inner `end for the reception of the adjacent extremity of an elongated plug-stem 17, retained in the plug by a pin 18, passing transversely through the wall of the plug and through the inserted end of the stem. At its rear or innerv end the stem 17 is threaded, as indicated at 19, for engagement with the internallythreaded socket 2O of a reciprocatory plunger 21, movable Within a plunger-cylinder 22, which latter is screwed upon the threaded inner end of the wall-pipe 2, the threads of the latter being preferably extended to a considerable distance from the inner end of the pipe to facilitate the adjustment of a lockingnut 23, which serves to draw the face-plate 5 IOO rigidlyagainst the outer face of the wall,

The plunger 21 is 'designed to be reciprocated within the cylinder 22 .by the rotation of the stem 17 to open or close the inner end of the bend 24, constituting a continuation of a water-supply pipe, andy coupled tothe rear l end of the cylinder 22 by a coupling 25, between which and the bend 24 is interposed suitable packing 26. 21, which is presented tothe inner end of the bend, constituting a valve-seat, isv covered by a mpressib1e'disk27, which when the plunger is urged to its closed position, as

Y shown in Fig. 2 of the drawings,`is compressed against the valve-seat to eectually close the inner end of the wall-pipe or, more propery speaking, the hydrant against further ingress of Water. In order to provide for the passage of water around the plunger when 'the latter is urged away from the valve-v seat, said plunger is provided with a peripheral series of longitudinal grooves or passages 28, and itsrotation within the cylinder" is prevented by an internal longitudinal guiderib 29, formed in the inner face of the cylinder 21 and engaging a vlongitudinal Vgroove 30, formed in the periphery of the plunger and closed at one end to vform a stop 31', which serves to limit the retraction of the plunger by engagement with the end of the -rib 29. It will be seen that this rib constitutes means oradevice for limiting the longitudinal movement of the plunger and for preventing axial movement thereof within the casing.

It will now be observed that the spring 16', mounted within the-plug-socket, will serve at all times to exert a pressure upon the plug forV the purposeof compressing the packingring or gasket lvto insure a water-tight connection around the plug of the hydrant and that this same force will'be exerted when the plug is closed to effect a water-tight connection between the plug and the inner end of the pipe 24 and,cfurther, that when the plunger is retracted by the rotation of the"plug the engagement of the stop 31 with the rib 29- will serve to cause the stem to be drawn longitudinally when further eifort is made to rotate the plug,l the effectof' this being to exert anadditional force tending to compress the gasket 15 t effect a connection even more :l

complete at the plug end of the hydrant when the waterfi's passing Vtherethrough to the hose- .Y nipple 6. lIt will alsoappear that when the moval ofwater from all exposed portions of the hydrant. v V

From the foregoing itw-ill be seen that have produced` a silnpleaud efci'ent wallhydrant by`means`of which the various obj-ects of the invention may be attained, but

although the construction illustrated and de-.r scribed appears at this time to be enti-rely satisfactory and preferable I wish to reserve The end 0f the; plunger theV right to effect such changes, modifications, and Variations of the Yconstruction and arrangement of parts as maybe comprehended within the scope of the protection prayed.
